General

Williams is an energy company committed to being the leader in providing infrastructure that safely delivers natural gas products to reliably fuel the clean energy economy. Its operations are located in the United States.

Williams’ interstate natural gas pipeline strategy is to create value by maximizing the utilization of its pipeline capacity by providing high-quality, low-cost transportation of natural gas to large and growing markets. Williams’ gas pipeline businesses’ interstate transmission and storage activities are subject to regulation by the FERC. As such, Williams’ rates and charges for the transportation of natural gas in interstate commerce, and the extension, expansion, or abandonment of jurisdictional facilities and accounting, among other things, are subject to regulation. The rates are established primarily through the FERC’s ratemaking process, but Williams may also negotiate rates with its customers pursuant to the terms of its tariffs and FERC policy. Changes in commodity prices and volumes transported have limited near-term impact on these revenues because the majority of the cost of service is recovered through firm capacity reservation charges in transportation rates.

The ongoing strategy of Williams’ midstream operations is to safely and reliably operate large-scale midstream infrastructure where its assets can be fully utilized and drive low per-unit costs. Williams focuses on consistently attracting new business by providing highly reliable service to its customers. These services include natural gas gathering, processing, treating, compression and storage; NGL fractionation, transportation and storage; and crude oil production handling and transportation, as well as marketing services for NGL, crude oil, and natural gas.

Consistent with the manner in which Williams’ CODM evaluates performance and allocates resources, Williams’ operations are conducted, managed, and presented within the following reportable segments: Transmission & Gulf of America, Northeast G&P, West, and Gas & NGL Marketing Services. All remaining business activities, including upstream operations, certain new energy ventures, and corporate activities, are included in Other. Williams’ reportable segments are comprised of the following business activities:

*•*Transmission & Gulf of America is comprised of the Transco, NWP, and MountainWest interstate natural gas pipelines, and their related natural gas storage facilities, as well as natural gas gathering and processing and crude oil production handling and transportation assets in the Gulf Coast region, including Discovery, a former 60 percent equity-method investment in which Williams acquired the remaining ownership interest in August 2024 (see Note 3 – Acquisitions and Divestitures), a 51 percent interest in Gulfstar One, and a 50 percent equity-method investment in Gulfstream. Transmission & Gulf of America also includes natural gas storage facilities and pipelines providing services in north Texas, and also in Louisiana and Mississippi related to the January 2024 Gulf Coast Storage Acquisition (see Note 3 – Acquisitions and Divestitures).

• Northeast G&P is comprised of midstream gathering, processing, and fractionation businesses in the Marcellus Shale region primarily in Pennsylvania and New York, and the Utica Shale region of eastern Ohio, as well as a 65 percent interest in Northeast JV which operates in West Virginia, Ohio, and

Management’s Discussion and Analysis (Continued)

Pennsylvania, a 66 percent interest in Cardinal which operates in Ohio, a 50 percent equity-method investment in Blue Racer, and Appalachia Midstream Investments.

• West is comprised of gas gathering, processing, and treating operations in the Rocky Mountain region of Colorado and Wyoming, the Barnett Shale region of north-central Texas, the Eagle Ford Shale region of south Texas, the Haynesville Shale region of east Texas and northwest Louisiana, the Mid-Continent region which includes the Anadarko and Permian basins, and the DJ Basin of Colorado. This segment also includes NGL storage facilities, an undivided 50 percent interest in an NGL fractionator near Conway, Kansas, and a 50 percent equity-method investment in OPPL.

• Gas & NGL Marketing Services is comprised of NGL and natural gas marketing and trading operations, which include risk management and transactions related to the storage and transportation of natural gas and NGLs on strategically positioned assets.

Unless indicated otherwise, the following discussion and analysis of results of operations and financial condition and liquidity relates to Williams’ current continuing operations and should be read in conjunction with the financial statements and combined notes thereto of this Form 10-Q and the Annual Report on Form 10-K for the year ended December 31, 2024 dated February 25, 2025.

Dividends

In March 2025, Williams paid a regular quarterly dividend of $0.50 per share.

Overview of Three Months Ended March 31, 2025

Net income (loss) attributable to The Williams Companies, Inc. for the three months ended March 31, 2025, increased $59 million compared to the three months ended March 31, 2024. Further discussion of the results is found in this report in the Results of Operations.

Recent Developments

Transco FERC Rate Case Filing

On August 30, 2024, Transco filed a general rate case with the FERC for an overall increase in rates and to comply with the terms of the settlement of its prior rate case. On September 30, 2024, the FERC issued an order accepting and suspending Transco’s general rate filing to be effective March 1, 2025, subject to refund and the outcome of hearing procedures established by the FERC. The order also accepted rate decreases for certain services to be effective as of October 1, 2024. Transco is engaged in settlement discussions with its customers and other intervening parties to resolve all aspects of the rate case. Transco has provided a reserve for rate refunds, which it believes is adequate for any refunds that may be required.

Data Center Power Projects

Williams continues to pursue projects to support the power demands created by new data center development, including an agreement with an unnamed large, investment-grade company to provide onsite natural gas and power generation infrastructure. See Expansion Projects for further discussion of the Socrates Power Solution Facilities.

Rimrock Asset Purchase

On January 31, 2025, Williams purchased a group of natural gas gathering and processing assets from Rimrock Energy Partners, LLC for approximately $325 million, to expand Williams’ gathering and processing footprint and create operational synergies in the DJ Basin in the West segment.

Management’s Discussion and Analysis (Continued)

Cogentrix Investment

In March 2025, Williams purchased a minority interest in Cogentrix Co-Investment Fund, LP (Cogentrix) for $153 million, which is accounted for as an equity-method investment within the Gas & NGL Marketing Services segment. Cogentrix owns interests in 11 natural gas power plants.

Expansion Project Updates

Significant expansion project updates for the period are described below. Ongoing major expansion projects are discussed later in Company Outlook.

Transmission & Gulf of America

Deepwater Whale Project

In August 2021, Williams reached an agreement with two third-parties to provide offshore natural gas gathering and crude oil transportation services as well as onshore natural gas processing services. The project expands its existing Western Gulf of America offshore infrastructure via a 26-mile gas lateral pipeline from the Whale platform to the existing Perdido gas pipeline and adds a new 124-mile oil pipeline from the Whale platform to Williams’ existing junction platform. This project was placed into service in January 2025.

Texas to Louisiana Energy Pathway

In January 2024, Transco received approval from the FERC for the project, which involves an expansion of Transco’s existing natural gas transmission system to provide firm transportation capacity from receipt points in south Texas to delivery points in Texas and Louisiana. Transco placed the project into service in April 2025. Under the project, Transco provides 364 Mdth/d of new firm transportation service through a combination of increasing capacity, converting interruptible capacity to firm, and utilizing existing capacity.

Southeast Energy Connector

In November 2023, Transco received approval from the FERC for the project, which involves an expansion of Transco’s existing natural gas transmission system to provide incremental firm transportation capacity from receipt points in Mississippi and Alabama to a delivery point in Alabama. Transco placed the project into service in April 2025. The project increases Transco’s capacity by 150 Mdth/d.

Company Outlook

Williams’ strategy is to provide a large-scale, reliable, and clean energy infrastructure designed to maximize the opportunities created by the vast supply of natural gas and natural gas products that exists in the United States. Williams accomplishes this by connecting the growing demand for cleaner fuels and feedstocks with our major positions in the premier natural gas and natural gas products supply basins. Williams continues to maintain a strong commitment to safety, environmental stewardship including seeking opportunities for renewable energy ventures, operational excellence, and customer satisfaction. Williams believes that accomplishing these goals will position it to deliver safe, reliable, clean energy services to its customers and an attractive return to shareholders. Williams’ business plan for 2025 includes a continued focus on earnings and cash flow growth.

In 2025, Williams’ operating results are expected to benefit from the continued growth in the Transmission & Gulf of America segment, primarily reflecting the impacts of numerous expansion projects at Transco and the Gulf of America. Additionally, growth in 2025 includes the impact of the Transco rate case and higher gathering and processing results associated with growth in the DJ Basin and the Northeast. Williams also expects increases in Haynesville Shale volumes, including partial year impact of the Louisiana Energy Gateway expansion project and higher expected results from its upstream operations, including the full year impact of the Crowheart Acquisition. Williams also expects to benefit from the recent equity investment in Cogentrix. These increases are

Management’s Discussion and Analysis (Continued)

partially offset by a modest increase in expenses and lower expected Eagle Ford results in our West segment related to minimum volume commitment reductions.

Williams seeks to maintain a strong financial position and liquidity, as well as manage a diversified portfolio of safe, clean, and reliable energy infrastructure assets that continue to serve key growth markets and supply basins in the United States. Williams’ growth capital and investment expenditures in 2025 are expected to range from $2.575 billion to $2.875 billion, excluding acquisitions. Growth capital spending in 2025 primarily includes the Socrates Power Solution Facilities project, projects supporting growth in the Haynesville Shale basin (including the Louisiana Energy Gateway expansion project), Transco expansions, all of which are fully contracted with firm transportation agreements, and projects supporting the Northeast G&P business. Williams also expects to invest capital in the development of its upstream oil and gas properties. In addition to growth capital and investment expenditures, Williams also remains committed to projects that maintain its assets for safe and reliable operations, as well as projects that reduce emissions, and meet legal, regulatory, and/or contractual commitments.

Potential risks and obstacles that could impact the execution of Williams’ plan include:

• A global recession, which could result in downturns in financial markets and commodity prices, as well as impact demand for natural gas and related products;

• Opposition to, and regulations affecting, our infrastructure projects, including the risk of delay or denial in permits and approvals needed for our projects;

• Counterparty credit and performance risk;

• Unexpected significant increases in capital expenditures or delays in capital project execution, including increases from inflation or delays caused by supply chain disruptions;

• Unexpected changes in customer drilling and production activities, which could negatively impact gathering and processing volumes;

• Lower than anticipated demand for natural gas and natural gas products which could result in lower-than-expected volumes, energy commodity prices, and margins;

• General economic, financial markets, or industry downturns, including increased inflation, interest rates, or tariffs;

• Physical damages to facilities, including damage to offshore facilities by weather-related events;

• Other risks set forth under Part I, Item 1A. Risk Factors. Risk Factors in the Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on February 25, 2025, as may be supplemented by disclosure in Part II, Item 1A. Risk Factors in subsequent Quarterly Reports on Form 10‑Q.

Three months ended March 31, 2025 vs. three months ended March 31, 2024

Service revenues increased primarily due to:

• Higher revenues associated with expansion projects at the Transmission & Gulf of America segment;

• Higher volumes from the August 2024 Discovery Acquisition at the Transmission & Gulf of America segment (See Note 3 – Acquisitions and Divestitures) and January 2025 Rimrock Asset Purchase at the West segment;

• Higher revenues associated with reimbursable expenses, which is offset by similar changes in the charges reflected in Other segment costs and expenses; partially offset by

Management’s Discussion and Analysis (Continued)

• Lower revenues in the Eagle Ford Shale region due to lower MVC revenue.

The net sum of Product sales and service revenues – commodity consideration, Product costs and net processing commodity expenses, and net realized gains and losses on commodity derivatives related to sales of product and shrink gas purchases for processing plants for the reportable segments comprise Commodity Margins. Service revenues - commodity consideration represent payments received in the form of commodities for processing services provided. Most of these commodity volumes are sold during the month processed and are offset within Product costs and net processing commodity expenses. The sum of Product sales and net realized gains and losses on commodity derivatives related to the upstream operations comprise Net realized product sales.

The Product sales and service revenues – commodity consideration increase primarily consists of:

• Higher marketing sales activities primarily related to higher NGLs marketing sales volumes and prices, including volumes from the Discovery Acquisition, and higher net natural gas marketing sales impacted by favorable prices and lower storage costs at the Gas & NGL Marketing Services segment;

• Higher product sales from upstream operations primarily related to higher volumes from the November 2024 Crowheart Acquisition at Other (See Note 3 – Acquisitions and Divestitures);

• Higher equity NGL sales and commodity consideration revenues associated with NGL production activity primarily driven by the Discovery Acquisition at the Transmission & Gulf of America segment.

As Williams is acting as agent for natural gas marketing customers, its natural gas marketing product sales are presented net of the related costs of those activities within the Gas & NGL Marketing Services segment.

Net gain (loss) from commodity derivatives includes realized and unrealized gains and losses from derivative instruments reflected within Total revenues primarily in the Gas & NGL Marketing Services segment, as well as at Other (see Note 9 – Commodity Derivatives).

Williams experiences significant earnings volatility from the fair value accounting required for the derivatives used to hedge a portion of the economic value of the underlying transportation and storage capacity portfolios as well as upstream-related production. However, the unrealized fair value measurement gains and losses are generally offset by valuation changes in the economic value of the underlying production or transportation and storage capacity contracts, which are not recognized until the underlying transaction occurs.

The Product costs and net processing commodity expenses increase primarily consists of:

• Higher marketing activities primarily related to higher NGLs marketing purchases, including from the Discovery Acquisition;

• Higher shrink natural gas purchases and commodity consideration costs associated with Williams’ equity NGL production activities primarily due to the Discovery Acquisition at the Transmission & Gulf of America segment.

Operating and maintenance expenses increased primarily due to operating costs of the assets acquired at the Transmission & Gulf of America and West segments, as well as at Other and higher electricity and fuel (substantially offset by higher Service revenues discussed above).

Depreciation, depletion, and amortization expenses increased primarily related to the assets acquired at the Transmission & Gulf of America and West segments, as well as at Other, and an increase at Transco related to additional assets placed in service.

Interest expense was primarily impacted by Williams’ 2024 and 2025 debt issuances, partially offset by 2024 and 2025 debt retirements (see Note 7 – Debt and Banking Arrangements) and the absence of imputed interest on deferred consideration obligations related to previous acquisitions.

Management’s Discussion and Analysis (Continued)

Period-Over-Period Operating Results – Williams’ Segments

Williams’ CODM evaluates segment operating performance based upon Modified EBITDA. Note 11 – Segment Disclosures includes a reconciliation of this non-GAAP measure to Income (loss) before income taxes. Management uses Modified EBITDA because it is an accepted financial indicator used by investors to compare company performance. In addition, management believes that this measure provides investors an enhanced perspective of the operating performance of Williams’ assets. Modified EBITDA should not be considered in isolation or as a substitute for a measure of performance prepared in accordance with GAAP.

Transmission & Gulf of America Modified EBITDA increased primarily due to higher Service revenues, partially offset by higher Other segment costs and expenses and lower Proportional Modified EBITDA of equity-method investments.

Service revenues increased primarily due to:

• A $44 million increase in Transco’s revenues primarily associated with expansion projects placed in service, notably Regional Energy Access in August 2024 and Southside Reliability Enhancement in November 2024;

*•*A $22 million increase primarily in gathering revenues due to the Discovery Acquisition in August 2024 (see Note 3 – Acquisitions and Divestitures);

• A $13 million increase in Gulf Coast Storage’s revenues primarily associated with higher storage rates;

• A $10 million increase in the Gulf Coast region primarily due to higher gathering and transportation volumes from the Whale expansion project that went in-service in January 2025 and production handling volumes from a new well at Gulfstar One in the Pickerel field, partially offset by shut-ins for maintenance activities at Devil’s Tower in the Taggart and Kodiak fields.

Management’s Discussion and Analysis (Continued)

Commodity margins increased primarily due to the Discovery Acquisition.

Other segment costs and expenses increased primarily due to:

*•*Higher operating expenses and administrative costs including increased operating costs resulting from Williams’ Discovery Acquisition and higher employee-related costs; partially offset by the absence of acquisition and transition costs related to Williams’ Gulf Coast Storage Acquisition in January 2024 (see Note 3 – Acquisitions and Divestitures);

*•*Unfavorable change in equity AFUDC primarily as a result of decreased capital expenditures at Williams’ regulated businesses;

• Unfavorable change in the amortization of regulatory assets and liabilities at Transco;

• Unfavorable change in the deferral of ARO-related depreciation at Transco.

Proportional Modified EBITDA of equity-method investments decreased primarily due to lower proportional results as Discovery was consolidated.

• An $8 million increase in revenues associated with reimbursable expenses, which is offset by similar changes in the charges reflected in Other segment costs and expenses.

Other segment costs and expenses increased primarily due to higher operating expenses, including higher electricity and fuel (substantially offset by higher Service revenues discussed above).

Management’s Discussion and Analysis (Continued)

Proportional Modified EBITDA of equity-method investments increased at Laurel Mountain Midstream, LLC primarily due to higher commodity-based gathering rates and at Blue Racer primarily due to annual rate escalations. The increase was partially offset by a decrease at Aux Sable Liquid Products LP due to the sale of Williams’ investment in the third quarter of 2024. Additionally, Appalachia Midstream Investments decreased primarily driven by lower volumes partially offset by higher gathering rates.

Gas & NGL Marketing Services Modified EBITDA increased primarily due to a favorable change in Net unrealized gain (loss) from commodity derivative instruments, partially offset by lower Commodity margins.

Commodity margins decreased $45 million primarily due to a $38 million decrease in Williams’ natural gas marketing margins, including $24 million of lower natural gas transportation capacity marketing margins due to unfavorable net realized pricing spreads. The decrease in its natural gas marketing margins also includes $14 million of lower natural gas storage marketing margins primarily driven by less favorable realized derivative gains, partially offset by lower storage fees and higher withdrawals from colder winter weather in first quarter 2025 compared to 2024.

The change in Net unrealized gain (loss) from commodity derivative instruments within Segment revenues and Net processing commodity expenses relates to derivative contracts that are not designated as hedges for accounting purposes. The change from 2024 is primarily due to a change in forward commodity prices relative to Williams’ hedge positions in 2025 compared to 2024.

Modified EBITDA from upstream operations, corporate, and other business activities decreased slightly primarily due to:

*•*A $32 million unfavorable change in Net unrealized gain (loss) from derivative instruments due to a change in forward commodity prices relative to hedge positions;

• A $9 million unfavorable change in other costs and expenses primarily related to upstream operations, including an increase from the Crowheart Acquisition in November 2024; partially offset by

*•*A $40 million increase in Net realized product sales from upstream operations primarily due to higher production volumes and higher net realized commodity prices associated with Williams’ Wamsutter region production, including the Crowheart Acquisition. The first quarter of 2025 also benefited from higher net realized commodity prices associated with Williams’ South Mansfield production in the Haynesville Shale region.

Variances due to the changes in natural gas prices and transportation volumes have little impact on revenues because, under our rate design methodology, the majority of overall cost of service is recovered through firm capacity reservation charges in Transco’s transportation rates.

Transco has cash out sales, which settle gas imbalances with shippers. In the course of providing transportation services to customers, Transco may receive different quantities of gas from shippers than the quantities delivered on behalf of those shippers. Additionally, Transco transports gas on various pipeline systems, which may deliver

Management’s Discussion and Analysis (Continued)

different quantities of gas on Transco’s behalf than the quantities of gas received from Transco. These transactions result in gas transportation and exchange imbalance receivables and payables. Transco’s tariff includes a method whereby the majority of transportation imbalances are settled on a monthly basis through cash out sales or purchases. The cash out sales have no impact on Transco’s operating income.

Revenues increased primarily due to:

• A $38 million increase in Natural gas transportation service revenues primarily due to additional capacity from placing the Regional Energy Access Expansion fully into service in August 2024, the impact of placing the Southside Reliability Enhancement into service in November 2024, higher electric power costs in 2025*,* and transportation rate increases effective March 1, 2025 partially offset by one less billing day in 2025. Electric power costs are recovered from our customers through transportation rates and are offset in Operating and maintenance expenses resulting in no net impact on our results of operations;

*•*A $7 million increase in Natural gas storage service revenues primarily due an increase in rates that became effective during the second quarter of 2024 and an increase in rates that became effective March 1, 2025;

• A $6 million decrease in Natural gas product sales due to lower cash-out volumes, partially offset by higher than average cash-out pricing, which directly offsets in Natural gas product costs resulting in no net impact on our results of operations;

Natural gas product costs increased, directly offsetting Natural gas product sales and resulting in no net impact on our results of operations.

Operating and maintenance expenses increased primarily due to higher employee-related costs and higher electric power costs. Electric power costs are recovered from customers through transportation rates and are offset in Natural gas transportation service revenues resulting in no net impact on results of operations.

Depreciation and amortization expenses increased as a result of an increase in depreciation rates effective March 1, 2025, and due to assets and expansion projects placed into service, partially offset by a decrease in ARO related depreciation (offset in Other income (expense) – net resulting in no net impact on Transco’s results of operations).

Other (income) expense – net changed unfavorably primarily driven by an unfavorable change associated with the deferral of ARO related depreciation (offset in Depreciation and amortization expenses resulting in no net impact on Transco’s results of operations), an unfavorable change in the amortization of ARO regulatory assets, an unfavorable change in the amortization of the regulatory pension liabilities, and an unfavorable change associated with disposition of certain project materials.

Interest income decreased due to a decrease in affiliated interest income on our advances to Williams due to a lower note receivable balance during 2025.

Allowance for equity and borrowed funds used during construction (AFUDC) decreased as a result of lower eligible capital expenditures.

Variances due to changes in natural gas prices and transportation volumes have little impact on revenues, because under our rate design methodology, the majority of overall cost of service is recovered through firm capacity reservation charges in our transportation rates.

Revenues decreased primarily due to:

• A $5 million decrease in Natural gas transportation service revenues primarily due to a decrease in long-term firm transportation;

• A $1 million decrease in Other service revenues from lower park and loan services.

Management’s Discussion and Analysis (Continued)

Other (income) expense - net changed favorably primarily as a result of projects transferred to capital.

Operating and maintenance expenses decreased primarily due to lower contract services related to pipeline maintenance inspection activities.

Other income (expense) – net decreased due to lower interest income earned on NWP’s advances to affiliates, which had a reduced balance in 2025.

Management’s Discussion and Analysis of Financial Condition and Liquidity

Outlook

Williams’ growth capital and investment expenditures in 2025 are expected to range from $2.575 billion to $2.875 billion, excluding acquisitions. Growth capital spending in 2025 primarily includes the Socrates Power Solution Facilities project, projects supporting growth in the Haynesville Shale basin (including Louisiana Energy Gateway expansion project), Transco expansions, all of which are fully contracted with firm transportation agreements, and projects supporting the Northeast G&P business. Williams also expects to invest capital in the development of its upstream oil and gas properties. In addition to growth capital and investment expenditures, Williams also remains committed to projects that maintain its assets for safe and reliable operations, as well as projects that reduce emissions, and meet legal, regulatory, and/or contractual commitments. Williams intends to fund substantially all planned 2025 capital spending with cash available after paying dividends. Williams retains the flexibility to adjust planned levels of growth capital and investment expenditures in response to changes in economic conditions or business opportunities including the repurchase of its common stock.

On January 9, 2025, Williams issued $1.5 billion of long-term debt and on January 15, 2025, Williams retired $750 million of long term debt (see Note 7 – Debt and Banking Arrangements).

On January 3, 2025, Williams paid the remaining $100 million of the Gulf Coast Storage Acquisition purchase price obligation (see Note 3 – Acquisitions and Divestitures).

As of March 31, 2025, Williams, including consolidated subsidiaries, has approximately $3.0 billion of long-term debt due within one year. Williams’ potential sources of liquidity available to address these maturities include cash on hand, proceeds from refinancing, the credit facility, or the commercial paper program, as well as proceeds from asset monetizations.

Liquidity

Williams expects to have sufficient liquidity to manage its businesses in 2025 based on forecasted levels of cash flow from operations and other sources of liquidity. Williams’ potential material internal and external sources and uses of liquidity are as follows:

Sources:
			Cash and cash equivalents on hand
			Cash generated from operations
			Distributions from equity-method investees
			Utilization of the credit facility and/or commercial paper program
			Cash proceeds from issuance of debt and/or equity securities
			Proceeds from asset monetizations
Uses:
			Working capital requirements
			Capital and investment expenditures
			Product costs
			Gas & NGL Marketing Services payments for transportation and storage capacity and gas supply
			Other operating costs including human capital expenses
			Quarterly dividends to shareholders
			Repayments of borrowings under the credit facility and/or commercial paper program
			Debt service payments, including payments of long-term debt
			Distributions to noncontrolling interests
			Share repurchase program

Management’s Discussion and Analysis (Continued)

As of March 31, 2025, Williams has approximately $24.1 billion of long-term debt due after one year. Potential sources of liquidity available to address these maturities include cash generated from operations, proceeds from refinancing, the credit facility, or the commercial paper program, as well as proceeds from asset monetizations.

Potential risks associated with Williams’ planned levels of liquidity discussed above include those previously discussed in Company Outlook*.*

As of March 31, 2025, Williams had a working capital deficit of $3.731 billion, including cash and cash equivalents and long-term debt due within one year. Williams available liquidity is as follows:

						March 31, 2025
						(Millions)
Cash and cash equivalents						$	100
Capacity available under Williams’ $3.75 billion credit facility, less amounts outstanding under Williams’ $3.5 billion commercial paper program (1)						3,428
						$	3,528

---

(1)In managing its available liquidity, Williams does not expect a maximum outstanding amount in excess of the capacity of its credit facility inclusive of any outstanding amounts under its commercial paper program. Williams had $322 million of Commercial paper (at par value) outstanding as of March 31, 2025. Through March 31, 2025, the highest amount outstanding under the commercial paper program and credit facility during 2025 was $475 million. Williams expects to be in compliance with the financial covenants associated with the credit facility for the March 31, 2025, reporting period.

Dividends

Williams increased the regular quarterly cash dividend to common stockholders from $0.4750 per share paid in each quarter of 2024, to $0.50 per share paid in March 2025.

Distributions from Equity-Method Investees

The organizational documents of entities in which Williams has an equity-method investment generally require periodic distributions of their available cash to their members. In each case, available cash is reduced, in part, by reserves appropriate for operating their respective businesses.

Credit Ratings

The interest rates at which Williams is able to borrow money are impacted by its credit ratings, which are currently as follows:

Rating Agency						Outlook						Senior Unsecured Debt Rating
S&P Global Ratings						Stable						BBB+
Moody’s Investors Service						Positive						Baa2
Fitch Ratings						Positive						BBB

In April 2025 Moody’s Investors Service changed its Outlook from Stable to Positive. In March 2025 S&P Global Ratings changed its Senior Unsecured Debt Rating to BBB+ with Stable Outlook. In January 2025, Fitch Ratings changed its Outlook from Stable to Positive.

These credit ratings are included for informational purposes and are not recommendations to buy, sell, or hold Williams securities, and each rating should be evaluated independently of any other rating. No assurance can be given that the credit rating agencies will continue to assign Williams investment-grade ratings even if it meets or exceeds their current criteria for investment-grade ratios. A downgrade of its credit ratings might increase Williams’

Management’s Discussion and Analysis (Continued)

future cost of borrowing and, if ratings were to fall below investment-grade, could require it to provide additional collateral to third parties, negatively impacting Williams’ available liquidity.

Sources (Uses) of Cash

The following table summarizes the sources (uses) of cash and cash equivalents for each of the periods presented in the Williams Consolidated Statement of Cash Flows:

Increase (decrease) in cash and cash equivalents									$	40					$	(1,483)

Operating activities

The factors that determine Williams’ operating activities are largely the same as those that affect Net income (loss), with the exception of noncash items such as Depreciation, depletion, and amortization, Provision (benefit) for deferred income taxes, Equity (earnings) losses, Net unrealized (gain) loss from commodity derivative instruments , Inventory write-downs, and Amortization of stock-based awards.

Williams’ Net cash provided (used) by operating activities for the three months ended March 31, 2025, increased from the same period in 2024 primarily due to favorable changes in net operating working capital and margin requirements, partially offset by lower distributions from equity-method investees.
